Hey, uh, Unidentified, the set clearly is equiped with the ability called RECKLESS, which prevents recoil damage. That being said, Head Smash and Flare Blitz are excellent choices, especially through a Choice Band that can boost speed. Just throwing it out there.

Please do the research before you comment. Rock Head is wat you are thinking about. Reckless would most likely cause more recoil damage.

EVs give the most physical bulk he can get. Curse increases his offensive capabilities while also raising his defense even more. Will-O-Wisp does residual damage while lowering my foe's attack. Hammer Arm is STAB ( I don't give a crap about speed. ) ( Sorry Speed Freak ) and Heat Crash is the other STAB option.

251 is the highest speed he can have. Even that isn't fast at all for a sweeper, considering that tons of pokemon have speeds over 300 and even dip into the 400s. Choice scarf also throws a new factor into the equation.

This works, but Gyro Ball is essentially useless in comparison to Hammer Arm as Steel types are only super-effective to two types, Ice and Rock, both are hit by Fighting types. Furthermore, Gyro Ball will do different amounts of damage to faster / slower Pokemon, with a maximum 150, Hammer Arm is always 150 power (100 x 1.5 for STAB= 150), and it also covers three more types than Gyro Ball.

Flame-charge boosts speed so you do not need a Scarf to sweep :D. Flare-blitz is STAB. Earthquake is coverage. Brick-break is coverage. This is not a suicide sweeper unlike most Emboar which is why he does not have reckless nor non STAB recoil moves.

Curse boosts Attack and Defense. Flare-blitz is STAB. Brick-break is STAB. Rock-slide/Stone-edge/Wild-charge/Magnitude your choice of Coverage, Rock-slide if you want more reliability, Stone-edge for more power, Wild-charge for Water-types, and Magnitude if you are willing to take the risk.

Well, this is for when Reckless comes out. It's a basic ResTalk set. Why ResTalk? Because Reckless will give him insane amout of recoil and he will die to easily. Nobody likes a suicide pig. Flare Blitz is his primary STAB, and damn, with Reckless, this thing will be OHKO'ing EVERYTHING. Second moveslot is up to you. Either choose Superpower, which lowers your Attack but is STAB or choose Head Smash which can be used for packing up as much recoil as possible and is coverage against Flying-types. Rest is for recovery while Sleep Talk allows you not to be a set-up bait and continue to attack with your insanely powerful moves. I didn't know what EVs to give him so I gave him 252 HP for some tanking Abilities, 252 Atk is a must while 4 Spd is just a filler. Adamant Nature is for more power. The Item choice is up to you. Either Expert Belt for an immediate OHKO when super-effective or Lefties, which can be helpful recovery while attacking.

But it doesn't work well to be honest, not trying to be a jerk.
Heat crash is horrible for Emboar, it might have about a 55 base power, despite him looking like a fatso, he doesn't way that much, and iron ball actually doesn't increase your weight. Flame Charge is decent if you want to rely on the speed boost, but honestly Emboar isn't bulky enough to set it up, and won't be likely to KO an opponent with it, Fling was a cool idea to hit psychic types, and Grass knot doesn't work with an all physical set to just throw it in there, perhaps something like earthquake, you can never go wrong with earthquake :]

Assurace + Hammer Arm Combo
To some movesets you can use Hammer Arm first to lowers the user's speed, so you will have a good chance to be the second to deals damage. Than use Assurance to be 100 power =)

Gyro Ball Power Up
I think everyone know it: use Curse and Hammer Arm to lowers speed and use Gyro Ball to deal high damage

I recommend use the Equilibrated moveset with Absorb Bulb in item, cause you cover all types(Psychic-type with Assurance, Water-type with Absorb Bulb and Flying- and Ground-type with Hidden Power(Ice)) and have some strong moves(Flare Blitz and Focus Blast)
